This checks that we are running in a Github actions workflow (as opposed to running locally or inside buildbot). We don't need to change what we're looking for (`GITHUB_STEP_SUMMARY` is implied by `GITHUB_ACTIONS`), but I felt changing it up made it more clear given we are now also running other scripts inside this conditional that don't have anything to do with the step summary.
